Ensengeka enkulu ey’Capacitive Touch Screen .IS: Substrate ye plexiglass emu-Layer, oluwuzi lwa firimu etangaavu ey’okutambuza luli mu ngeri y’emu ku ngulu ez’omunda n’ez’ebweru eza plexiglass, era kkooni enfunda era empanvu eteekebwa ku nsonda ennya eza firimu ya conductive etangaavu ku ngulu okw’ebweru. Electrode. Omusingi gwayo ogw’okukola guli: engalo bw’ekwata ku .Capacitive Touch Screen ., siginiini ya frequency eya waggulu- eyungibwa ku kifo ekikola. Mu kiseera kino, engalo n’ekifo ekikola ku .Touch screen .Kola capacitor ya coupling, nga eno yenkana kondakita, kubanga waliwo obubonero bwa frequency obw’amaanyi-ku ngulu w’okukola. Akasannyalazo akatono kakubiddwa ku kifo we gukwata. Akasannyalazo kano akatono kakulukuta okuva mu bisannyalazo ku nsonda ennya ez’Touch screen .. Akasannyalazo akakulukuta mu buuma obuna kageraageranye n’obuwanvu bwa layini okuva ku lunwe okutuuka mu nsonda ennya. Mu kubala, omuwendo gw’enkwatagana y’ekifo ky’okukwatagana guyinza okufunibwa.
OmuCapacitive Touch Screen .Kiyinza okutwalibwa mu ngeri ennyangu nga screen ekoleddwa layers nnya eza composite screens: layer ey’ebweru ennyo ye layeri ekuuma endabirwamu, egobererwa layer etambuza, layer eyokusatu ye non-exconductive glass screen, era layer eyokuna ey’omunda ennyo nayo layeri ya conductive. Ekisenge ekitambuza amasannyalaze eky’omunda kye layeri y’okuziyiza, ekola omulimu gw’okuziyiza obubonero bw’amasannyalaze obw’omunda. Ekisenge ekiyisa amasannyalaze ekya wakati kye kitundu ekikulu eky’okukwata ku ssirini yonna. Waliwo ebikulembera ebitereevu ku nsonda oba ku mabbali ennya okuzuula ekifo we bakwatako.
Olususu olusinga okubikka waggulu lwa ndabirwamu oba polyethylene terephthalate (PET). Ekirungi kya PET kiri nti .Touch screen .Asobola okufuulibwa omugonvu, ate ku ludda olulala, ya buseere okusinga ebikozesebwa eby’obuveera n’endabirwamu ebiriwo. Omusuwa oguziyiza (insulating layer) gwa ndabirwamu (0.4-1mm), firimu ey’obutonde (10-100um), eyeesiiga, n’oluwuzi lw’empewo. Olususu olusinga obukulu ye layeri ya indium tin oxide (ITO). Obugumu bwa ITO obumanyiddwa buli 50-100nm, era obuziyiza bwayo obw’ekipande buba nga 100-300 ohm range. Enkola n’ensengeka ya ITO ey’ebitundu bisatu erina kinene ky’ekola ku .Capacitive Touch Screens .. Kikwatagana butereevu n’ebikulu ebibiri ebikulu parameters .Touch Screens .: inductive capacitance (engalo ne waggulu ITO) ne parasitic capacitance (wakati wa ITO waggulu ne wansi layers, wakati wa ITO eya wansi ne display screen). mu masekkati).
Ensengeka y’e .Capacitive Touch Screen .Okusinga okusiiga oluwuzi lw’omubiri gwa firimu olutangalijja ku ssirini y’endabirwamu, n’oluvannyuma n’oteekamu endabirwamu ekuuma ebweru wa layeri ya kondakita. Dizayini y’endabirwamu bbiri esobola okukuuma ddala layeri ya kondakita ne sensa, era obutambuzibwa bw’ekitangaala buba waggulu. Asobola okuwagira obulungi multi-Touch.
OmuCapacitive Touch Screen .ekolebwako obusannyalazo obuwanvu era obufunda ku njuyi zonna ennya ez’Touch screen .Okukola ekifo ky’amasannyalaze ekya AC ekya wansi-Voltage mu mubiri oguyisa amasannyalaze. Nga okwata ku ssirini, olw’amasannyalaze g’omubiri gw’omuntu, wajja kubaawo okukyusakyusa wakati w’olugalo n’oluwuzi lwa kondakita.
Nga capacitor coupling, current okuva mu electrodes ennya-zijja okukulukuta okutuuka ku contacts, era amaanyi ga current ga inversely proportional to the distance wakati w'engalo ne electrode. controller esangibwa oluvannyuma lwa .Touch screen .ejja kubala omugerageranyo n'amaanyi ga kasasiro okubala obulungi ekifo ky'ekifo eky'okukwatako . Endabirwamu ey’emirundi ebiri eya .Capacitive Touch Screen .tekuuma kondakita ne sensa zokka, naye era ziziyiza ensonga z’obutonde ez’ebweru okukosaTouch screen .. ne bwe kiba nti screen efuuse kivundu, nfuufu oba amafuta amabala, .Capacitive Touch Screen .Akyayinza okubala obulungi ekifo ky’okukwata.
Okuva capacitance bweyawukana n’ekitundu ky’okukwatagana ne dielectric of the medium, obutebenkevu bwayo bubi era drift phenomenon etera okubaawo. kino ekika kya .Touch screen .Kisaanira omutendera gw'okulongoosa enkola y'okukola .
